Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990694, here are decompositions:

101 + 990593 = 990694
191 + 990503 = 990694
197 + 990497 = 990694
311 + 990383 = 990694
317 + 990377 = 990694
401 + 990293 = 990694
557 + 990137 = 990694
641 + 990053 = 990694

Showing the first eight; more decompositions exist.
